Title: Improvements in the manufacture and production of condensation and polymerisation products of hydrocarbons
IPC: C10M131/12
Filed: 1933-04-05
Abstract: In preparing condensation or polymerisation products suitable as lubricating oils or for addition to lubricating oils to improve the setting point or temperature-viscosity curve as described in Specification 349,071, by halogenating hard or soft paraffin wax and condensing the resultant product in the presence of aluminium or zinc chloride or other reagent, the initial material or the halogenated products are separated into fractions by fractional distillation, fractional deposition by cooling, or by heating in stages the solidified product and sweating out different products at each stage. In separating the chlorinated products by cooling in presence of solvents e.g. acetone, the monochlor compound is first separated, then the dichlor compound and subsequently the trichlor compound. The condensation may be effected in presence of inert diluents such as middle oil or of substances such as naphthalene, olefines or petroleum or tar fractions which take part in the reaction.  The chlorination may be carried out to obtain mainly a monochlor product, for example, by atomizing paraffin wax in an atmosphere of chlorine while irradiating with ultra-violet light.ALSO:In preparing condensation or polymerization products suitable as lubricating oils or for addition to lubricating oils to improve the setting point or temperature-viscosity curve, as described in Specification 349,071 by halogenating hard or soft paraffin wax and condensing the resulting product in the presence of aluminium or zinc chloride or other reagent, the initial material or the halogenated products are separated into fractions by fractional distillation, fractional deposition by cooling or by heating in stages the solidified product and sweating out different products at each stage.

Abstract: 376,775. Alternating -current commutator machines. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 7, 1931, No. 10273. Convention date, April 8, 1930. [Class 35.] The salient pole stator of a three-phase commutator machine excited by alternating currents of different phase has a compensating winding with a coil pitch or mean pitch of 180 electrical degrees and the armature winding has the same or nearly the same pitch, the main pole pitch being 60 electrical degrees, each coil of the exciting winding embracing a main pole without embracing the adjacent commutating poles. Where a three-phase set of brushes is employed, lap windings of 180‹ pitch may be employed for the armature and compensating windings, the exciting winding E and commutating pole winding W being arranged as shown in the Figure where two coils situated 180‹ apart belong to one phase. The number of conductors in series per phase of the compensating winding should equal one-half the number of conductors in series per phase of the armature winding but, where a six-phase sets of brushes is employed these two numbers must be equal. Shunt, main current or separate excitation or a combination of these may be used.

Title: A machine for making pleated metal foil capsules
Inventor: RAILTON DENIS EASTHOPE
IPC: B65B35/26
Filed: 1949-04-26
Abstract: 688,046. Shaping or stamping metal-foil capsules. IDEAL CAPSULES, Ltd., and RAILTON, D. E. April 26, 1950 [April 26, 1949], No. 10318/50. Divided out of 688,024. Addition to 663,860. Class 100 (ii). In a machine for forming pleated metal foil capsules from a continuous web, as in Specification 663,860, the finished capsules are fed into a tray which is moved to discharge its contents at the completion of a predetermined number of capsuling operations. Fig. 2 shows the rear of the revolving head of the machine described in Specification 688,024 and which carries the capsules step by step past a forming position, a smoothing and embossing position to an ejecting position C where the capsules are ejected axially so that they nest together in a long tray 55. The tray is pivoted at 56 and when swung downwardly about its pivot, the nested capsules are dropped on to the table 57 and roll into packages. The mechanism for dropping the tray is actuated from the oscillating lever 43, which, as described in Specification 688,024, rocks once for each capsuling operation. Each time the lever 43 rocks, pawl 64 advances the ratchet wheel 63 one tooth. 65 is a retaining pawl. The ratchet wheel has a radial notch 70 near its periphery. Bearing against the peripheral face of the ratchet wheel is a tooth on the lever 66, which is freely pivoted on the horizontal bar 6. Fixed to the upper end of lever 66 is a laterally projecting pin 76. to which is secured the mounting for an eccentric 82 connected by linkage 83 to the lever 61 carrying the tray 55. At each complete revolution of the ratchet wheel, the tooth on lever 66 drops into the slot 70 and the lever 66 moves under spring pressure so that a projection 77<SP>1</SP> on the eccentric moves into the path of a constantly rotating member having an arcuate groove 81, which carries the eccentric round one revolution so dropping the tray against the action of spring 58 to discharge its contents. The slot 70 is the width of one tooth of the ratchet wheel, so that the parts are restored to their normal positions by the time the next capsule is ejected into tray 55. By substituting a ratchet wheel with the appropriate number of teeth the number of capsules in the stack before discharge may be varied.

Title: Automatic gain control
IPC: H04N5/52
Filed: 1945-04-24
Abstract: 59 7, 0 5 0. Automatic gain control. FARNSWORTH TELEVISION & RADIO CORPORATION. April 24, 1945, No. 10335. Convention date, July 1, 1944. [Classes 40 (iii) and 40 (v)] An automatic gain control system is designed so as to maintain constant the peak-to-peak value of the signals. The invention is described in its application to a television amplifier in which the output from the image dissector (not shown) is amplified in an electron multiplier 1 having load resistors 6, 7. The desired image signals are taken across resistor 7 and fed through the cathode-anode space of an impedance valve 9 to a broad band amplifier 10 and the further stages 17. Resistance 6 is shunted by a byepass capacity 8 and is connected to the grid of valve 9. In this way the impedance of valve 9 is made to vary inversely with the average value of the image signals received from tube 1, and so the average value of the instantaneous image signal voltages received by valve 10 from resistance 7 through impedance valve 9 is kept constant. Alternatively, the impedance valve 9 may be arranged in shunt across load 7. In that case the polarity of the applied control voltage is reversed. Blanking and synchronising signals from source 18 may be applied in negative polarity through condenser 19 to the grid of valve 9, an isolating resistance 20 being provided.
